SPECIFICATION' fOTmillg part of Letters Patent NO. 723,824, dated March31, 1903. Application led December 2,1901. Serial No. 84.369. (Nomodel.)

To all whom t may concern.- v Beitknown that i, BENSON S. BULLIs, acitizen of the United States, residing at the city appertains to makeand use the same, referio ence being had to the ings, forming part ofwhich- Figure 1 is vided withainy present 'accompanying drawlhisspecification,

an elevation of a window proinvention. Fig. 2 is l5 a transversevertical sectional elevation of the same. Fig. 3,is an View showing thelower the screen-roller fram parts. Fig. 4 is a top zo frame.

enlarged fragmentary sash-bar, the sill, and

e with` its supported plan view of the roller- Fig. 51's a transversesectional elevat-ion of the parts illustrated in Fig. 3. Fig. 6 is anend View of one end of the rollerframe and roller.

Fig. 7 is a fragmentary View, chiefly in `longitudinal section, of saidz5 end of the 8 is an end view of "roller-frame and roller.

the nature of that shown in Fig. 7,

roller-frame and the roller.

the opposite end ot' Fig. 9 is a view ofv Fig. said end of the frameshown in Fig. 8; and Fig. 3o 10 is a detail view illustrating thebracket which engages the dog-carrying end of the roller, the end of thespring-actuated rod being shown in position to be engaged by saidbracket.

Myinvention relates to improvements in wlndow-sc`reens, my objects beingto provide al bracket for the dog roller of such of usual type can be ei4o effectively held out of -carrying end of the construction thatspring-rollers nployed and the dogs notches in the end of the usualspring-actu ated rod,toprovide me ans for readily mounting the screensupon the sash or the windowframe,and to provide an apron or Hap whicheiectually covers the space between the roller and its supporting-bar,but causes little wear of the screen.

To these ends and also to improve general y upon devices Otth echaracter indicated my inventionconsists inthe various matters 5ohereinafter described and claimed. I 'Referrimer now more particularlytoy the drawings, l represents the window frame or casing; 2, the innersash; 3, the outersash; 4, the sill, and 5 the top bar of 'the frame. 55Screens 6 and? are connected to the outer sash in such manner that vtheopeningsbetween the sash andthe sill or the sash and the said top barare protected by said screens in all positionsof the sash. Said screensare 6o mounted upon rollers S, which are carried byt frames each ofwhich comprises a top strip il and end brackets 10 and 11, by which the'rollers are supported. Thus a'i'oller'with its screen can be readilymounted said frames and the frame then fastened in position, therebyavoiding the diculty Of mounting a roller itself'in a small space or ata point difficult Of access. In the'einbodiment of my invention hereillustrated Queimiler-frame is secured tothe iop bar5`o thewindow-casing, and the lower edge of the screen carried by said rolleris fastened to thelupper rail l2 of the outer sash, while am other ofsaid roller-frames is secured tbl'the 75 under face of the lowersash-rail 13, the'free end of the screen being'provided with as trip 14,which has buttons or the like 15, adapted to be received by eyebolts 16,fastened Ato the sill l. In order to provide for readily"8o fasteningthe roller-frame `upon the sash-rail 3,1" aid rail is provided withturn-hooks 17, which when turned into one position enter slots 1S in theopposite sides of the frame-l strip 9 as said strip is moved intoposition 85 against the sash-rail, and when said hooks are turned tobring their angle-fingers 19 un der the-strip 9 the frame is firmly butremovably secured. The frames being mounted in the manner described andthe rollers having '9o springs of usual type under constant tension, itwill be apparent that as the sash 3 is raised or lowered one screen isunwonnd to protect the space between the sash and the windowframe whilethe other screen is wound upon its roller. Y Manifestly a slight spacemust be left between a roller and the strip 9 or other framer upon oneOff65 member below which said roller is supported, and in order toprotect this space an apron or flap 20, of screen-cloth' or. othersuitable hmaterial, is attached to the strip 9 over about thelongitudinal axis of the roller md depends upon the cloth upon said'roller. A light strip 21, of wood or the like, is provided upon the freeedge of the apron and serves to weight said edge suiiciently to hold itupon the wound cloth, thus causing the apron to eiectually protect thespace, and said strip alsoV prevents the free edge of the apronfromwrinkling and thereby forming openings for fiies and other insects. Theapron being suspended as described and bein sr iiexible readily fallsupon the side of the roller toward which said roller is being ro-=rated, and thus exerts but little wear upon the screen as it is beingWound or unwound. The roller has projecting' from one end the usualspring-actuated rod 22, in 'whose projecting end are formed thecustomary notches 23 for thedogs 24, while the other end of the rolleris provided with an opening 25'. The said notches are in the sides ofthe rod and have their endsopen. Oneof th-e brackets l (the bracket 10)upon the roller-frame has a piu 2G, which enters said opening 25, whilethe bracket ll has upon its inner face two inwardly-projecting pins27,which snugiyen ter the notchesd in the springactuated rod, thusiirrnly holding said rod against rotation .and preventing the dogs 24from entering said notches. The outer portions of the pins 27 aresmoothed and rounded in order to 4insure easy pass/age of the dogs overthe same.

I amY aware' that many minor changes in the construction, arrangement,andcombination of the several parts of my device can be m'ade andsubstituted for those herein shown Vthis 29th. day of November, 1901.

and described without in the least departing v from the nature andprinciple of my inven tion. Y

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters l. The combination with a spring-roller having dogsand a rod provided with notches, of a brackethaving projecting membersadapted t'o seat in said notches, the outer surfaces of said projectingmembers being formed to lie fush with the exterior surface of theroller-rod to constitute a smooth unbroken surface, substantially as andfor the purpose described.

2. The combination with a yspringroller having dogs and a rod providedwith notches, of a bracket, oppositely-arranged fingers 27 projectingoutwardly from the bracket adaptved to seat in said notches, the outersurfaces unbroken surface, substantially as and for the purposedescribed.

In testimony whereof I hereunto affix my signature, in the presence oftwo wtnessex BENSON S. BULLIS.
